AI agents call get_object_property to retrieve information from Unreal without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'get_' prefix strongly suggests this tool retrieves property information without modifying state. The empty description prevents full certainty, but the consistent naming convention with other read-only query tools on the server (get_actor_info, get_level_info) indicates this is a data retrieval operation with no side effects.
From the tool's definition Tool name 'get_object_property' with the 'get_' prefix indicates a retrieval operation. The sibling tools on the server include destructive (delete_actor) and write operations (create_basic_castle, modify_actor), while this tool follows the naming pattern of…
Documented attack patterns abuse exactly the kind of access get_object_property gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Unreal, and nothing reaches the server without passing your rules. This is the rule we recommend for get_object_property:
{
"version": "1",
"default": "deny",
"tools": {
"get_object_property": {}
}
}get_object_property is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_object_property. It is categorised as a Read tool in the Unreal MCP Server, which means it retrieves data without modifying state.
Register the Unreal MCP server in PolicyLayer and add a rule for get_object_property: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Unreal. Nothing to install.
get_object_property is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_object_property rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_object_property. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_object_property is provided by the Unreal MCP server (runeape-sats/unreal-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
